Slush Casting is a traditional method of permanent mold casting process, where the molten metal is not allowed to completely solidify in the mold. When the desired thickness in obtained, the remaining molten metal in poured out.
The tolerance produced by shell moulding process of casting is
Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section.
Extrusion is Consists of pressing the metal inside a chamber to force it out by high pressure through an orifice which is shaped to provide the desired form of the finished part.
An example of desirable work hardening is that which occurs in metalworking processes that intentionally induce plastic deformation to exact a shape change. These processes are known as cold working or cold forming processes.
The cold working of the metal increases the hardness, yield strength and tensile strength.
The process used to improve fatigue resistance of the metal by setting up compressive stresses in its surface, is known as
Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals.
For arc welding direct current is used.
In backhand welding, the angle between the welding rod and the work is ________ as compared to forehand welding.
